Guennadi Liakhovetski 08298f0612 sh: explicitly include sh_dma.h in setup-sh7722.c
setup-sh7722.c defines several objects, whose types are defined in
sh_dma.h, so, it has to be included explicitly.

Guennadi Liakhovetski 4dc4c51675 serial: sh-sci: fix compilation breakage, when DMA is enabled
A recent commit:

commit d6fa5a4e7a
Author: Guennadi Liakhovetski <g.liakhovetski@gmx.de>
    serial: sh-sci: prepare for conversion to the shdma base library

is not sufficient to update the sh-sci driver to the new shdma driver
layout. This caused compilation breakage, when CONFIG_SERIAL_SH_SCI_DMA
is enabled. This patch trivially fixes the problem by updating the DMA
descriptor manipulation code.

Guennadi Liakhovetski d9adcc1286 mmc: prohibit card detection when host is not ready
Currently mmc host drivers have to decide whether to enable card
detection before calling mmc_add_host() -- in which case a card
insertion event can arrive before the host has been completely
initialised -- or after mmc_add_host(), in which case the initial
card detection can be problematic.

This patch adds an explicit indication of when card detection should
not be carried out. With it in place enabling card detection before
calling mmc_add_host() should be safe. Similarly, disabling it again
after calling mmc_remove_host() will avoid any races.

necessary, since the TMIO MMC driver itself checks for NULL callbacks. This

Guennadi Liakhovetski 89d71486b2 sh: select the fixed regulator driver on several boards
On systems, using regulators to supply power to devices, if the REGULATOR
Kconfig option is disabled, regulator API stubs will be used, which often
suffices to bring a default configuration up. If REGULATOR is enabled but
respective regulator drivers are inactive, the real regulator API calls
will be used, which in the absence of drivers will fail to provide
services. This patch prevents such a problem on sh-mobile boards by
forcing REGULATOR_FIXED_VOLTAGE on if REGULATOR is selected.

Drivers for several devices on mackerel, including all SDHI instances, the
MMCIF controller and the SMSC9220 ethernet chip use regulators to control
power supply to their devices. MMC drivers need to be able to at least
retrieve voltage values from supplying regulators, whereas the smsc911x
driver only enables and disables chip power supplies without further looking
at them. This patch adds two fixed voltage regulators to describe 1.8V and
3.3V supplies on the board and a dummy regulator for SMSC9220.

Guennadi Liakhovetski dfad84aeab regulator: support multiple dummy fixed regulators
Currently regulator_register_fixed() uses a constant name to register a
fixed dummy regulator. This is sufficient in principle, since there is no
reason to register multiple such regulators. The user can simply supply all
consumers in one array and use it to initialise such a regulator. However,
in some cases it can be convenient to register multiple such regulators.
This is also a prerequisite for the upcoming patch, that will add a voltage
parameter to this function. The original function is provided as a wrapper
macro.

Guennadi Liakhovetski 2f9a0c880d [media] V4L: soc-camera: protect hosts during probing from overzealous user-space
If multiple clients are registered on a single camera host interface,
the user-space hot-plug software can try to access the one, that probed
first, before probing of the second one has completed. This can be
handled by individual host drivers, but it is even better to hold back
the user-space until all the probing on this host has completed. This
fixes a race on ecovec with two clients registered on the CEU1 host, which
otherwise triggers a BUG() in sh_mobile_ceu_remove_device().

Guennadi Liakhovetski 0e9f480bb5 mmc: cd-gpio: protect against NULL context in mmc_cd_gpio_free()
Do not oops, even if mmc_cd_gpio_free() is mistakenly called on a driver
cleanup path, even though a previous call to mmc_cd_gpio_request() failed.

Guennadi Liakhovetski 4eb80146f8 sh: ecovec: switch SDHI controllers to card polling
Polling for card hotplug events is a better option than using SDHI native
hotplug interrupt, because the latter option forces the controller to stay
permanently powered up and enabled.
